264acd9ec9 7144 - tmp: redo checks for function outputs 
This isn't done, but an intermediate snapshot seems worth capturing.

Back in March (commit 6082), I made a plan to check writes to function
outputs using liveness analysis. I've been shying away from actually acting
on this plan ever since. In recent weeks I've had this gap bite me three
times.

Returning to the problem now, I think I don't actually need to compute
variable liveness. The compiler can, I think, do the same thing for output
registers whether their variables are alive or dead. The new rule is this:

Once a register gets a function output written to it, no local is popped
into it. Instead of popping outer locals to the register, we simply increment
the stack and keep going.

Since the function output will continue to live on the vars stack past
this point (see clean-up-block), any attempts to read shadowed variables
will throw an error as usual.

This rule is also now easy to explain to people, I think. "You wrote the
function output. Now the register can't be used for anything else."

It's really cool that this works (if it does). Another fruit from "Mu's
lovely property."

c5e1cbc4ce 7129 - tile: allow bindings anywhere 
Amazing how easy this was. And it does feel more intuitive. If I decide
at some point that I want to bind something to a name I don't usually want
to lose the entire line after that point.

It also sidesteps for now the thorny question of whether to permit organically
switching to a new line (rather than using the 'name value' hotkey), and
how that should work.

Some more helpers that I want to avoid using, but they help me gain confidence
in the current implementation of file handles. Manual test:

  "x" open dup read swap read

Assumes there's a file called `x` in the current directory that contains
at least two (short!) lines.

Turns out I've been including some unnecessary files when building apps/mu!

Treeshaken stats before:
  LoC 26258 => 9717
  LoC including common libraries: 29736 => 12719
  binary size: 406K  => 79K

After:
  LoC 26258 => 9717
  LoC including common libraries: 28322 => 12370
  binary size: 406K  => 77K

So our treeshaking isn't perfect. No surprise there..

The treeshaken build also starts to fail without the one-liner change to
mu.subx, which looks like a bug in the treeshaker.

Left arrow key out of an expanded word now working.

Still to fix: left arrow key out of the first word in the first word.

ae6340f225 6991 - tile: nested calls now expanding 
I just needed to remove an obsolete guardrail in render-line.

Still seeing some bugs with left-arrow when playing around with the full
expansion of `1 2+`.

Bring back definitions for 1+ and 2+. Expanding nested calls still doesn't
work.

Oh, of course. I can't compare the word with the word at the cursor. Not
even its interned pointer. We have to track the call path.

e8367b2bc2 6987 - left-arrow to jump to caller/callee 
Starting to work. I'm still seeing problems in lines with multiple expanded
calls, but perhaps that's a rendering issue.

The code is absolutely ghastly.

Cursor now stays on the right row as we bounce in and out of function calls.

5ba974b4e5 6982 - right-arrow now moves into expanded calls 
Rendering is still ugly. Cursor isn't on the right row. But the hard part
is behind us.

This was a stupid mistake in function-body, and it happened because I've
been getting lazy and passing (addr handle) objects when I should be passing
in "constant" addr objects.

I'm not sure why I was so resistant to debugging by print here. I spent
3 days waffling about with this bug.

Use the fake-screen infrastructure we already have for non-interactive
mode.

We don't have tests yet in the tile prototype, mostly because we don't
yet feel confident about what desired behavior should be. But it's still
helpful to have a non-interactive mode for tracking down segfaults.

Snapshot. We've gotten arrow keys navigating, but segfault when getting
to the second word in an expanded function call body.
